Paediatric HeartMate 3™, the Uneventful 22-Month Journey to Transplantation of a 14-Year-Old-Patient-Time for Prolonged LVAD Support in Children?

Abstract

We report on a 14-year-old patient who was supported for nearly two years with an ic-LVAD and managed to complete his journey to transplantation without a single complication. Although mechanical assist device support is available for children up to 20 kg in body weight, availability is limited to paracorporeal devices. Intracorporal (ic) left ventricular assist devices (LVADs) for infants in the suitable weight class are a viable option as a bridge-to-transplant, where they make up more than 50% of transplant candidates in their category. A teenager with 59 kg body weight was newly diagnosed with DCM and listed for heart transplantation. After initially being on VA-ECMO, an Abbott HeartMate 3 LVAD with postoperative temporary RVAD support was initialised. RV-support was maintained for 10 days. The further postoperative course was uneventful, and he was discharged on day 98. He was seen regularly in the outpatient department and integrated into school routine again, following the extensive training of his classmates and the responsible school staff. After a total of 672 days on support, he was successfully transplanted. There were no unplanned admissions, thrombotic nor bleeding events, as well as no driveline infection, even though the patient participated in sport classes at school.
